The ordered mouse is very small, but fits comfortably in your hand. For a continuous use you have to expect loads of palm rejection, because (at least for me, with long fingers), the mouse is not in the palm of your hand, but on the fingers rests (spinning handle). Thus, it makes sense for larger hands more for occasional use ... except one uses a gel cushion -or also has enough Horn on the palm heel.
The mouse looks very chic in red color from which keys can be pressed pleasant and the scroll wheel moves leichläufig and makes no noise. Practically, the cable reel, which makes an individual length of the cable possible. However, they wound up on not really, so that the cable is hanging out a bit out of character. But is only an optical flaw, is beside the point in terms of operability. The mouse can be very pleasant to move from the desktop and is quite fast there. Who the movements should be too fast, which can of course about the Mouse Options in the Control Panel regulate (in my OS Windows). Even without Mouse Pad motion detection optics and scanning is very good, it works even on dark wood surfaces or even on a plain light-brown envelope.
All in all a good buy, have the mouse just a day in operation and it has been performing flawlessly. One shortcoming is the rolling up of the cable. Nevertheless, I decided -bislang- for the right product at an affordable price. If still should change something in the functioning, I will this grudge here.
What really is very annoying, is the manufacturer's packaging. It is a tightly welded products made of hard plastic, which is also equipped with a pair of scissors is very difficult to open. The packaging itself is with a utility knife is very difficult to open. I also had nice often with other electronic products (especially with SD card). But that's not the problem of the trader but exclusively by the manufacturer. Here you can still make improvements immensely in terms of customer-friendliness. But well, who buys cheap, has also a lot to accept.
Supplement 03/2015
The mouse still works as before, only the cable reel is now broken, although I do not often use it. But well, levered retractor with pliers and removed from the cable. Now I have a working mouse, the cable can not be rolled up. Anyway ... the actual function is not affected. For the price and the service life probably seems to be in order of the "defect".
